 | Gondolo, Paolo | Indirect detection of dark matter in km-size neutrino telescopes | Neutrino telescopes of kilometer size are currently being planned. They will be two or three orders of magnitude bigger than presently operating detectors, but they will have a much higher muon energy threshold. We discuss the trade-off between area and energy threshold for indirect detection of neu... | Neutrino telescopes; Energy threshold; Neutralino annihilations; Supersymmetric models | 1998-11 |

 | Gondolo, Paolo | Limits on R-parity violation from cosmic ray antiprotons | We constrain the hadronic R-parity violating couplings in extensions to the minimal supersymmetric standard model. These interactions violate baryon and lepton number, and allow the lightest superpartner (LSP) to decay into standard model particles. The observed flux of cosmic ray antiprotons plac... | R-parity; Supersymmetric models | 1998-06 |

 | Gondolo, Paolo | Neutralino decay rates with explicit R-parity violation | We compute the neutralino decay rate in the minimal supersymmetric standard model with the addition of explicit R-parity violation. We include the complete squark and slepton mixing matrices, previously neglected, and we improve and correct published formulas. These decays are relevant to accelerat... | Neutralinos; R-parity; Decay rates; Sfermions | 1998-03 |

 | Wu, Yong-Shi | Noncommutative gauge theories in matrix theory | We present a general framework for matrix theory compactified on a quotient space Rn/G, with G a discrete group of Euclidean motions in R". The general solution to the quotient conditions gives a gauge theory on a noncommutative space. We characterize the resulting noncommutative gauge theory in t... | Matrix theory; Noncommutative space | 1998-09 |

 | DeTar, Carleton | Quenched hadron spectroscopy with improved staggered quark action | We investigate light hadron spectroscopy with an improved quenched staggered quark action. We compare the results obtained with an improved gauge plus an improved quark action, an improved gauge plus standard quark action, and the standard gauge plus standard quark action. Most of the improvement ... | Staggered quarks; Chiral symmetry; Flavor symmetry | 1998-07 |

 | DeTar, Carleton | String breaking in lattice quantum chromodynamics | The separation of a heavy quark and antiquark pair leads to the formation of a tube of flux, or string, which should break in the presence of light quark-antiquark pairs. This expected zero temperature phenomenon has proven elusive in simulations of lattice QCD. We present simulation results that sh... | String breaking; Antiquarks; Polyakov loop; Dynamical fermions | 1998-12 |

 | Wu, Yong-Shi | Towards a noncommutative geometric approach to matrix compactification | In this paper we study generic M(atrix) theory compactifications that are specified by a set of quotient conditions. A procedure is proposed which both associates an algebra to each compactification and leads deductively to general solutions for the matrix variables. The notion of noncommutative g... | Matrix theory; Compactification; Noncommutativity; Orbifolds; Orientifolds; Spacetime; Klein bottle; Gauge theory; Torus | 1998-07 |

 | Wu, Yong-Shi | Type-IIB-string-M-theory duality and longitudinal membranes in M(atrix) theory | In this paper we study duality properties of the M(atrix) theory compactified on a circle. We present evidence for the equivalence of this theory to the strong coupling limit of type-IIB string theory compactified on a circle. In the M(atrix) theory context, our evidence for this duality consists of... | Matrix theory; Longitudinal membranes; Compactification; String theory; Duality | 1998-02 |
